But this most recent kind of attack does not only involve social engineering but also relies on the misuse of a previously undocumented feature in the WoW interface. Imagine the following situation: Most probably, the attacker does not have neither those items nor a valid code for them. Subsequently, the victim does not receive any valid code and no item at all. The WoW interface e. But, feeding your chat window with this single line of code changes the behavior of the WoW interface. The function RemoveExtraSpaces is called on every new chat message a player receives.
The command mentioned above replaces the RemoveExtraSpaces function with the RunScript function, which is called hooking in software development. Once the original function is overwritten, every new chat message is interpreted as Lua code and immediately executed. The scenario is as follows. Instead of earning some magic items, the player turned himself into the victim:. What we have shown above, is a rather harmless example for this misuse, a Proof of Concept PoC.
This is very similar to behavior usual Trojan horses show on computers — they pose as something useful and then unfold their malicious behavior.
After the victim opened the backdoor to his interface, the attacker sends the following chat message:. The fact that the chat function does not work anymore, could look suspicious to the victim and maybe even make him restart the game. To understand the intention of this code one needs to know that WoW add-ons have the possibility to communicate via a hidden channel locally and remotely. The script creates a frame line 2; z to which one can set different properties.
Only the one who knows the chosen prefix is now able to secretly control the hijacked interface of the victim. This is comparable to a password for a backdoor. Even though we are talking about add-ons that can communicate via a hidden channel, an attacked player does not need to have any add-ons installed for the attack to work. This is a new development regarding WoW in-game attacks. An attacker usually would not have the chance to know such detailed information about other players.
In WoW, players have the possibility to trade items among each other. For this, the two characters need to be in physical proximity and can then exchange items. He can virtually rob the victim. Our scenario described a social engineering attack paired with a technical attack.
Manipulated clients might be misused to send convincing chat messages to other players, e. As we all know, messages from friends and colleagues are considered trustworthy. As simple as it sounds: Do not enter the script code into your chat window! Question each and every request to type in any message into your chat window. In the given example, we talked about an attacking in-game character who belonged to a popular guild.
Well, he posed as a member of such a popular guild, but he actually was not. You might already be familiar with such typo squatting techniques from phishing attacks.
Furthermore, be careful when downloading add-ons from third parties: It is conceivable that some might add the line of code in question to their add-ons and therefore use the extras as a kind of vehicle for the attack.
The glitch itself can only be fixed by Blizzard. They have to make sure that overwriting such a special function becomes impossible. They reacted to the script attacks and have implemented a warning message after the input of a script, but before it is executed:. To re-activate it, one has to manually delete one line of code in the configuration… really only this one line:. Code that needs to be deleted: Some may still know the adorable little pocket critters that were all the rage in the late 90s.
Premium SMS messages were the first attacks on Android users — almost six years ago, malware with this Instead of earning some magic items, the player turned himself into the victim: The attacker sends a chat message to the victim. After the victim opened the backdoor to his interface, the attacker sends the following chat message: The attacker establishes a new communication channel. The warning message Blizzard added to their newest patch.
